Abstract: PROBLEM TO BE SOLVED: To obtain a small-sized electro-optic retroreflection scanning mode equipped with all necessary components and a completely built-in type. SOLUTION: This retroreflection scanning module is equipped with a base part, a 1st circuit board 416, and a 2nd circuit board 418 which is fitted almost at right angles to the 1st circuit board 416. The base part supports a light radiation body, which generates a scanning beam and an optical component which directs and converges light energy. A radiated beam reflection body reflects the light from a return mirror 212 on a reflection body fitted to a drive part for an oscillation body. The reflection body changes the direction of the beam to a mark to be read. The mark is scanned with the beam through the vibration of the reflection body. The reflected light is directed to the vibrating reflection body and made incident on a converging mirror 204, before reaching a detector 206. The detector 206 included in the module detects the light reflected from the mark scanned with the beam. The beam and the visual field of the detector 206 are scanned at the same time. Various implementation styles of vibration drive and optical arrangement are disclosed to make the scanning module small-sized.

Abstract: PROBLEM TO BE SOLVED: To reduce the size and weight of a component to be used for converging reflected light by generating the scanning motion of a light beam. SOLUTION: A first module provided with a laser for emitting a laser light beam and a photodiode for sensing light reflected from a bar code symbol is attached to a support independently away from a second support provided with a movable reflector and a driving device for moving the reflector. The reflector is attached on a pair of tension elements comprising a permanent loop advantageously for enabling to vibrate.

Abstract: PROBLEM TO BE SOLVED: To provide a small-sized assembly for scanning a display mark which contains vibratile parts having functions of focusing, sweeping of light beam crossing the display mark and further correction of scan aberration, if necessary. SOLUTION: A laser diode emitting the beam is inserted in a center of an opening of a wound electric coil in order to save a space. A magnet on the parts interacts with the coil to cause vibration. A floating flexure returns the parts to an equilibrium position.

Abstract: A first module (10), including a laser for emitting a laser beam and a photodiode for detecting light reflected from a bar code symbol, is independently mounted on a support (14a) in a spaced relation to a second module (12) which includes a movable reflector and a drive for moving the reflector. The reflector is advantageously mounted for oscillation on a pair of taut elements constituting an endless band.

Abstract: A compact assembly for electro-optically scanning indicia includes an oscillatable component operative for focusing, and for sweeping, a light beam across the indicia and, optionally, for correcting for scan aberration. A laser diode for emitting the beam is inserted into a central opening surrounded by an electromagnetic coil to conserve space. A magnet on the component interacts with the coil to effect oscillation. A floating flexure returns the component to an equilibrium position.

Abstract: The laser diode (133) of an optical scanning system (100) is located in a separate unit (130) and light therefrom carried to a remote scan head (110) via an optical fiber (150). This reduces the size and weight of the scan head (110) and reduces the temperature sensitivity of the scan head (110). The scan head (110) may include an optical sensor (117) for detecting light reflected from scanned symbols.

Abstract: An integrated scanner for scanning a barcode is formed on a common substrate. The scanner may include a micro-machined mirror, a laser diode, and a detector, mounted on a single substrate or several connected substrates. Lenses can be used to focus a laser beam from the laser diode as well as expand a laser beam deflected by the micro-machined mirror. The scanner may also scan a barcode without using a micro-machined mirror by rotating the laser diode.
